Abstract (en)
[origin: EP0736820A1] In a color electrophotographic printer, an intermediate transfer belt (15) is provided to layer toner images of a plurality of colors, and the toner images on the belt are transferred onto a paper sheet. In order to remove a paper sheet when a paper jam happens, a door (27) is provided in a case of the printer, while a cover (20',38') is provided to protect a transfer region where the intermediate transfer belt contacts with a paper sheet for transferring the toner images. When the door (27) is opened, the cover (38') moves to cover a portion of the surface of the intermediate transfer belt exposed to the door. When the jammed paper sheet is removed, the image forming process is resumed immediately on the toner images on the intermediate transfer belt. Further, an intermediate transfer unit (35') including the intermediate transfer belt (15) and the cover (20',38') detachable from the printer may be provided. In a modified example, a transfer member which is connected to a transfer member is provided instead of the cover, and when the door is opened, the transfer member covers the surface of the intermediate transfer belt. <IMAGE>
